The powerful 1520 Watt laboratory power supply, with a height of just 1U, can be stacked directly on top of each other, eliminating the need for any air gaps above or below, effectively fitting within 1U. Output voltages of 0 - 40 V/DC and output currents of 0 - 38 A can be set directly on the device or remotely via the built-in RS232/RS485 interface. All important functions can also be programmed through analog inputs (control voltage 0-5V, 0-10V, control current 4-20 mA, or via an external resistor for digital control, e.g., through LabView and LabWindows, with corresponding drivers available). High-resolution 16-bit A/D and D/A converters enable very precise adjustment and programming. The rotary knobs on the device can be switched between coarse and fine adjustment. A dual digital display shows the current values as well as various status information (including Over Voltage Protection, Under Voltage Limit, overload mode, address settings), and a monitor output provides corresponding analog voltages (0-5V or 0-10V) for external monitoring. Of course, the device can operate as both a constant voltage and constant current source, automatically switching between these modes as needed. Multiple devices can be connected in series or parallel. The GEN/H type has half the size of 19" racks.
